This invention relates. tocar framel sup-H ports and journal boxes and comprises all the featuresof novelty `herein disclosed. `An objectI of theinvention is to provide an imjusting seat.A plate for transferring loadfrom. a car frame member to a journal box.. To

" 'these-end-s and. to improve generally` and in detail upon devicesI of this'A charactergthe inj ventioir also consists in. the various matters.

In Figs.` l and 3V the numeral 1) indicates a shaft or axle with a bearing sleeve'- 12 for i roller bearings 1.4 having end rings I6.. The

rollers'run on. an outer racewayprovided byv asleeve 18` in the straight cylindrical bore of a housing, herein shown as a journal box 20. The inner end of. the box is. closed by a capA 22 having a flange 23 engaging aV gasket, at the end of the box.. Thefcap vhas grease grooves24 adjacent to the axle and a groove 2.6K arranged to. receive oil thrown off from a rib.- 28 on the axle and drain it into the bottoniy of the box. The cap also-basa flat annular face 36A toy engage the adjacent bearing end` ring 16 and lugs 32 to locate the outer race sleeve 18. Externally, the cap has ai relief,l groove 4f` to letoil:Y out of the bearing sleeve 18 and conduct it to the bottom of the a central cross sectional view of box,fthus helping to prevent theroil from.l building up a pressure tending to induce'r leakage at the axle. Thecap has lugs .36,tof engage boltfheads on boltsr38 which. traverse.l straight through the boxand have nuts 40 to secure an end cap 42'against the other endof the box. The cap l2 has an internal flange46 at the outer end ofthe bearings and carriesv a thrust block. 48 oppositegto-the end of thev axle. vBoth sides of the box have pedestal flanges 50 with crowned surfaces whichv are preferably chilled as indicated at 52. Portions ofY the sides of thebox. are also chille as.. indicatedat 54. f i

`Thel top of the boxfhas araisedportion.v

the upper surface ofwhich. isV chilled or hardened. A detachable block or seat plate 62is1rockably mountedonth-e surface 66 and is held fromshiftingfbodilyin anydirectionby interIitti-ng lugs and ycavities on the seat plate and box.v Preferably` the surface 60 is cylindrical. or otherwise slightly crowed longitudinally-ofthe axle and box on a curve.v i

of largeradius. The lower surface 64 of the seat plate is also shown cylindrically crownedA longitudinally of the. box to .rock onrrthe. crowned surface 60 although the crowning:

may sometimes be confined to one surface alone. The lnterfitting lugs and: cavitles preferably comprise downwardly extending j lugs 66 at opposite sides ofthe seatI plate,.the lugs entering cavities 68 inthe box at opposite sides of the longitudinal center. embrace walls 70. at the sides of the raised portion of the box and so hold the seat plate from shifting bodily cros'swi'se ofthe box.

The end walls of the lugs are slightly crowned vertically as indicated at 69 and are confined between: corresponding concave surfaces. 71

on the end walls of the cavities 68. .This

construction holds the seat plate from-shifting bodily longitudinally of the box but al` lows the seat plate and box to havearelative rocking movementlongitudinally. Some clearance may exist between the lugs and cavitiesV for manufacturing reasons but this Will allow' only a very slight twisting of the seat plate on the box around a vertical axis without permitting any material bodily dis,- placement. The seat plate 62 hasend. flanges lll."

72 and transversely crowned surfaces 7 4 meeting at a central rib 7 6 which enters a slot or recess of a frame member such as an equalizer bar and allows a slight transverse rocking of the seat plate and box with respect to Ythc equalizer bar. Slots 78 at the sides of the box are traversed by the bolts 38. As indicated in Fig. 4,'the upper surface of the .seat plate 62 may be adapted for two oppositely extending equalizer bars by providing two lugs 80 and crowning the upper surfaces as at 82 Figs. 5, 6 and 7 show a modification. The inner end cap 86 comprises an attaching Hange 88 and a pair of grooves 90 and 92on opposite sides of an annular rib 94. A sealing washer or guard 96 of U-shaped section isv` held against a shoulder of the axle and its two legs98 and 100 extend into the grooves`90 and 92, respectively. vThis effectively pre- `vents egress of oil along the axle and any water getting into the groove 90 may run out through a hole (not shown) at the bottom. The top` of the box is provided with a rocking seat plate 102 for a pairof parallel equalizer bars 104 which are seated on crowned surfaces in slots 106 having central ribs 108. rIhe pedestal flanges 110 on the box arefcloser together to permit the pedestals to pass between the equalizer bars but, in other respects, the construction is substantially th-e same as shown in Figs; 1,2 and V3.
